Look at the line
No matter what color of the fish line, the surface of the line must be shiny (except for braided lines), transparent lines cannot have color, and colored lines
No whitening.
Draw out a section of the line first, and then gently touch it with your finger. Check whether the thickness of the fishing line is even and whether the surface is flat; Put the fishing line into the palm of your hand to slightly squeeze it, release the palm, and check how the fishing line recovers after being stressed.
After the fish line is soaked in water, its water absorption can be tested; In the process of use, the fishing line will absorb water. Once the fishing line absorbs water, the sensitivity of the string group will decline, and a good fishing line should not absorb water.
